China announced a breakthrough invention: Applying technology to create 'unprecedentedly durable' materials

The process is simple and cost-effective but creates materials that can be easily applied in transportation and aerospace .

A group of Chinese scientists has developed a technique that makes aluminum alloys more heat resistant, improving the limitations of this lightweight metal. This is an important component in fields such as aerospace and transportation.

Aluminum alloys are known for their low density, exceptionally high strength and corrosion resistance. But so far, their heat resistance has been relatively limited. Traditional aluminum alloys usually withstand temperatures around 350 degrees Celsius. At 400 degrees Celsius, the mechanical properties of this material will quickly decline, limiting the ability to use them in product design. no universe.

This new aluminum alloy is more than 6 times more durable than traditional aluminum alloys.

By adding nanoparticles to conventional aluminum alloys , scientists from the school of materials science and engineering at Tianjin University (TJU) have created a stronger , workable aluminum alloy. good even at much higher temperatures.

In an official announcement earlier this month, TJU said this new aluminum alloy is more than 6 times more durable than traditional aluminum alloys and surpasses all the best aluminum-based materials recorded worldwide. .

"This manufacturing process is simple, cost-effective and easily scalable for industrial production, making it highly valuable for industrial applications," said lead researcher He Chunnian .

The research expert added that the team is collaborating with research organizations and industry leaders to promote the development of heat-resistant aluminum alloys for applications in aerospace engines, and hopes the material This will soon be used in industry.

The research was published on April 26 in the journal Nature Materials.

As mentioned above, the heat resistance of aluminum alloys is improved by combining with highly stable oxide nanoparticles. In addition to being cheap, particles with a melting temperature of over 1,000 degrees Celsius also have outstanding durability, thermal conductivity, heat resistance, oxidation resistance and corrosion resistance.

The process of incorporating nanoparticles into alloys to create oxide dispersion enhanced (ODS) alloys has shown promise. In 2022, NASA revealed a similar method to produce the nickel-based Nasa GRX-810 alloy, which can withstand temperatures of 1,093 degrees Celsius.

According to NASA's website, this method has significantly improved the durability of parts used in aviation and space exploration, providing better and longer-lasting performance.
